T 0 all whom it may concern:

Be it known that we, Gnome PATRICK BRYAN and OSWA'LD ERNEST Aninsrno ve, both subjects of the King of Great Britain 5 and Ireland, residing at Sale and Altrinchain, near Manchester, England, respectively, have invented new and useful lImprovementsiin Embossing and Pressing "Machines, of which the following -is aspecification. j

This invention relates to machines primarily directed to embossing materials such as cardboard or millboard, in which a heavy even pressure is required over a comparatively large area, and has ior its main object to provide an hydraulic press operated from a suita'ble source of pressure for such purpose. -Further objects are to provide means to indicate the correct penetration of the type into the {cardboard and the position of the platen relatively to the press head and also improved means to position and hold the embossing dies on the press table. An embossing and pressing machine made in accordance with this invention comprises means for indicating the degree of impre sion effected, said means comprising engaging members respectively mounted onthe sta on ryand moving par s o the machine and engaging faces between the said members adapted toreceive .a sample of the material being embossed, and the e gaging members may be adjacent to the press table and so located with respect thereto as to receive between the engaging faces an ove hanging portion or extension of the 1naterial on the press table, and the table may be slidably mounted on the machine with means for locatingseotions of the table suecessively in register with the platen, and clampingineans may be provided for secu ing the dies to the table.

In order .to ensure that the embossing shall be uniform and the dies penetrate to the correct depth, an indicator is provide which Joy means of a multiplying motion indicates to .fine limits the penetration of the embossingd esalld the same nd cator may be adapted .or a separate indicato provided to indicate the elative position of the platen to the press head s that th pressure is only released to an XtBILtL'SHfl bient for the withdrawal of the show card .1 4- er a n 716,818-

or for ehanging'the position of the same to obviate undue movement of the platen.

The invention will be more particularly described by the aid of the accompanying dr ings, w e ein Fig. is apart sectional'elevation of an embossing press constructed according to the inve tion- Fig. 2 is a side elevation otFig. 1.

Fig. is a view showing means for positioning the type, and

"Fig; 4 is anend view of Fig. 3.

Referring to th dr ings the t le is provided with guides 6 seouredthereto and s iding on the vertica y mo ing memb r 16 resting on or se u ed to t e P ung oi the "hydrau c cy in er 0 whic t r rests upon the base d of the machine, said ba being mou on a sui b and not shown. At each. corner of the'base a pillar e is "bolted,the four pillars constituting ver tical guides for the comparativelylong slipper bearing 6 formed in the member 1).

Bolted (to the top of the pillars 6 is the press :top or head f.

" The s id ng table .ai adopte t be m d along the W ys 5 un i l pa ha e we istered With the head f, said table being adapted to receive the embossing dies and proportioned so that the embossing can be done in any desired number of-stages. The table is of a size such that the type can be set up so that the cardboard can be embossed in sections and according tothe drawings the table a will allow of a showcard five times the size of the press-head being em- "bossed by moving the table in successive stages with adiflerent part under the press jheado; means such as the indicator -h on a spindle 7 2, rota-tafbly rnounted on the bed Z) being provided to register with markings on the table guides 6 so as to gauge the correct positions t e of, and if de i d a catch leve Zi may be pr v ed on t e spind e .h o engage s cc ss e not es in the guides o th t b e a t p siti e y hold it in the correct position at all stages.

.Uponthe tab e a, lines 1 re m rke o .facilitate the se tingnp of h typ wh c nsnal y giue the eto- I des th ie :iIlfiYibfi fseeiinedttothe ab eby pring-c amp- ;ingstnips ,j, the dies s anding iip above th clampsland the ends of said .elamp be ng tnrned down and adapted to spring over the edges of the table a as clearly seen in Fig. 4.

In practice, assuming the type to be set up and a sheet of paper which it is desired to impress into the cardboard and a.

sheet of cardboard placed over said type it is essential that the impression shall be the same over all parts of the cardboard and to very fine limits in order that the letters shall be embossed regularly to the same extent all over the card and just sufiicient to separate the paper, which is usually glazed, evenly around the edges of the embossed letters and embed the edges-to an extent sutficient to cause the separated portions to adhere to the card without fracturing or tearing the parts lying on the raised letters.

To ensure the correct impression being given every time to the card an lndicaton is provided which is conveniently constructed as shown. Referring to Figs l and 2, a plunger is is slidably mounted in the head 7, being normally forced down wardly by means of a spring Z, the lower end of the said plungenforming an anvil and the upper end being connected to one end of a pivoted lever inthe other end m of which moves over a fixed. scale a and constitutes an indicator.

Formed in one with or a-ttachedfto the member I) is an anvil 0 in vertical-alignment with the plunger is and the top of which is flush with the tops of the embossing type. Two nuts in are provided on the upper end of the plunger is to form an adjustable stop to limit the downward movement of the plunger in the head 7' so that the anvils will separate with the. lowering of the'member b. When a card is being embossed a strip of card of the same thick ness is placed on the anvil 0 or a portion.

of the card itself may overhang the table and lie thereon so that when the table is raised in the act of embossing a card, im-

mediately said card engages the press head,

the lJBfOlGJHGDtlOIK-Bd} strip or portiorrof card engages the pendant head of. the plunger and causes the; same to ascend and impart movement to the lever at so that the end m indicates on the scale a the extent of the impression. If desired the lever 177. may beadapted to indicate the relative position of the platen to the press head or a separate lever 79 pivotally' connected to the press head for this purpose, said lever moving over a scale 9 under the influence of a link connected to the moving member I). r

Pressure water is forced into thev cylinder 0 by means of a hand pump, not shown, or supplied thereto from any other and suitable source, and if desired the member .7) may be mounted as a fixture and the head a f, and associated parts, adapted to reciprocate, in which case, said head, would be provided with a counterbalanceweight or springs to raise it ofi" the work.

By these means a press is provided for embossing showcards and the like which can moved whereby it is more robust and has a longer life..

hat we claim is I 1. In an embossing and pressing machine, means for indicating the depth of impresson effected, said means comprising engaging members respectively mounted on the stationary and moving parts of the machine,

movement-indicating means operated by one offs-aid members, and engaging faces be tween the said members adapted to receive a sample of the material being embossed. so as to be separated by the thickness there-- of during the embossing operation.

I 2;; Inan embossing and pressing machine, means for indicating the depth of .rmprem,

sion effected, said means comprising engaging members respectively mounted on the stationary and moving parts of the machine, and movement-indicating means operated by one of said engaging members, said engaging members being adjacent to the press table and having engaging faces located to receive between them an overhanging portion or extension of the material on the, press table, so as to be separated' thereby during the embossing operation.

3. In an embossing and pressing machine, means for indicating the depth of impression effected. said means comprising a plunger slidably mounted in the fixed head of the press, an indicator lever connected to the upper end' of said plunger, a return spring on said plunger acting to move it into its lowest position, and an anvil on fplunger slidably mounted in the fixed head ofthe press, an indicator lever connected to the upper end of said plunger, a return spring on said plunger acting to move it into its lowest position, an adjustable stop on said plunger to limit its downward movement, and an anvil on the lower end of said plunger constituting one engaging member coasting with an anvil on the platen or moving member of the press constituting the other engaging member, which engaging members are adapted to receive between them a sample of the material being embossed so as to be separated by the thickness thereof during the embossing operation, as set forth.

In testimony whereof We have signed our names to this specification.
